ieee802154: hwsim: Fix memory leak in hwsim_add_one
No matter from hwsim_remove or hwsim_del_radio_nl, hwsim_del fails to
remove the entry in the edges list. Take the example below, phy0, phy1
and e0 will be deleted, resulting in e1 not freed and accessed in the
future.
hwsim_phys
|
------------------------------
| |
phy0 (edges) phy1 (edges)
----> e1 (idx = 1) ----> e0 (idx = 0)
Fix this by deleting and freeing all the entries in the edges list
between hwsim_edge_unsubscribe_me and list_del(&phy->list).
